Not too many mistakes, but a 5kg lighter and a modern bike is on the wish list.
S-1: after comparing splits, I think this is the best route choice.
2-3: soft legs after the climb 2x30s
3-4 still suffering and make unnessary detour 1m
5: a very fast DH, good performance
6: good
7: too long detour 1 min faster staight
8: the direct trail (middle of vinyard) is faster another 1 m 30
